| sugar-phosphatase | <enzyme> Acts on a wide range of hexosephosphates, pentosephosphates and oligosaccharidesphosphates Registry number: EC 3.1.3.23 Synonym: sugar phosphate phosphohydrolase, hexose-6-phosphate phosphohydrolase (26 Jun 1999) |
|---|---|
| sugar tumour | A benign clear cell tumour of the lung containing abundant glycogen. (05 Mar 2000) |
| deoxy sugar | A sugar containing fewer oxygen atoms than carbon atoms and in which, consequently, one or more carbons in the molecule lack an attached hydroxyl group. Synonym: desoxy sugar. (05 Mar 2000) |
| desoxy sugar | A sugar containing fewer oxygen atoms than carbon atoms and in which, consequently, one or more carbons in the molecule lack an attached hydroxyl group. Synonym: desoxy sugar. (05 Mar 2000) |
| invert sugar | Subjected to chemical inversion: inverted. (18 Nov 1997) |
| oil sugar | A class of preparations made by the trituration of a volatile oil (anise, fennel, lemon, etc.) with sugar; used as a diluent or corrigent of powerful or bad tasting drugs in powder form. Synonym: oil sugar. Origin: oleo-+ G. Saccharon, sugar (05 Mar 2000) |
| fruit sugar | D-fructose. See: fructose. (05 Mar 2000) |
| absolute intensity threshold acuity | The minimal light that can be seen. (05 Mar 2000) |
| absolute threshold | The lowest limit of any perception whatever. Compare: differential threshold. Synonym: stimulus threshold. (05 Mar 2000) |
| achromatic threshold | Threshold of visual sensation, the minimal light intensity evoking a visual sensation. Synonym: achromatic threshold, minimum light threshold. (05 Mar 2000) |
| anaerobic threshold | The oxygen consumption level above which aerobic energy production is supplemented by anaerobic mechanisms during exercise, resulting in a sustained increase in lactate concentration and metabolic acidosis. The anaerobic threshold is affected by factors that modify oxygen delivery to the tissues; it is low in patients with heart disease. Methods of measurement include direct measure of lactate concentration, direct measurement of bicarbonate concentration, and gas exchange measurements. (12 Dec 1998) |
| auditory threshold | The audibility limit of discriminating sound intensity and pitch. (12 Dec 1998) |
| brightness difference threshold | The smallest difference that can be perceived as a difference in brightness. Synonym: light difference. (05 Mar 2000) |
| pain threshold | Amount of stimulation required before the sensation of pain is experienced. (12 Dec 1998) |
| galvanic threshold | The minimal strength of an electrical stimulus of indefinite duration that is able to cause excitation of a tissue, e.g., muscle or nerve. See: chronaxie. Synonym: galvanic threshold. Origin: rheo-+ G. Basis, a base (05 Mar 2000) |
